Secrets

 * 1) Go to the eastern part of the map (right of the map start), next to the spinning tube with a cacodemon inside it. If you look at the walkway, you might spot a target switch on the stone wall. Shoot it to open a passage south of the cacodemon tube, where you can find ammo, health and a plasma rifle and energy cell packs, guarded by an ambush. (sector 1664)
 * 2) To get the soul sphere near the center of the map, climb and traverse the purple walkways to it. While doing so, look between the two spinning tubes with cacodemons inside them and shoot the target switch. The platforms near the steps will lower and you can claim the soul sphere. Look out for stealth alien troopers (on Ultra-Violence or higher) or zombiemen (on lower skill levels) when you attempt to take it, though. (sector 114)
 * 3) Drop off to the east from where the yellow key is to an area with a plasma rifle and boxes of rockets, along with a cyberdemon and an arachnotron. Notice the megasphere on a ledge in the center of this M-shaped walkway. The switch at the far end of this area lowers a teleporter, but also the megasphere as well. Run back to get it. (sector 475)
